DISCUSSION
First of all, for my osmosis lab, I submerged 2 eggs with vinegar, so that the shell of the egg can dissolve. Acetic acid from vinegar reacts to the calcium carbonate in the shell of the egg and dissolves the shell of the egg. After it dissolves, it leaves a membrane that can let some of the particles in and leave some of them out.
When they are submerged in two different substances, the appearance of the egg changed. The mass of the egg before being submerged in to water was 63.1 g, but after 24 hours, being submerged in the water, the mass of the egg was 71.5 g. It also affected the volume of water. The volume of the water decreased from 150mL to 132mL. This can be interpreted that part of its water went inside the egg by osmosis. Different from water, the egg that was submerged in the honey shrinked. The mass of egg decreased from 60.7g to 57.6g. The volume of the honey has increased from 150mL to 165mL. Same with water, the osmosis happened. The water particles moved from high concentration to low concentration, which was to egg from honey.
I think was a small mistake during the lab. The egg that was submerged in the honey’s mass before submerged had difference of 2.9g. But the volume of it had only difference of 15mL, which I didn’t expected it to be. We might have left some honey on the surface of the egg before we measured the mass of it. If I were to do this project again, I would use food dye to figure out the result of osmosis more accurately.
